After you order and drive away, I’ll find the app hours later still tracking me and using GPS. I almost always have to force close the app.
Then the next time I use it the previous order won’t have cleared out despite me picking it up, and I’ll have to go in and “cancel” the order.
The coupons are good though. For a week or two it was giving 30% off, and almost always has a 20% off coupon.
